Nice video. I always thought running in place was a bug too. It looks silly. You should remove it.
Please change/fix these three things:
1) When a hero levels up the perk you pick (the button) is hard to see. It's just an outline you can barely see. Make it apparent (maybe another background color).
2) Fix the mouse cursor in tactical battle. It gets stuck in some mode (cancel, ranged attack, cast spell) and still shows that when you hover on something else which doesn't make sense. In fact, make sure the mouse cursor is always updated to the right context during the game. This is a problem since E:WoM. It looks unprofessional.
3) Add your increment gain/loss of gildar/mana/prestige in the top bar like: 523 (+12) gildar. I asked for this several times. You need this information during the game literally hundreds of times. Doing it this way will save A LOT of mouse pointer travel time for us.
